Freezer runs but does not get cold enough; food is soft or thawing; compressor runs almost continuously.

Safety first: Unplug the freezer before cleaning coils or working near the compressor.

Steps:

• Clean condenser coils: Pull the freezer away from the wall. Use a coil brush and vacuum to remove dust from the condenser coils located at the back or underneath.
• Check condenser fan: If your Insignia model has a condenser fan near the compressor, ensure it spins freely and runs when the compressor is on. Replace the condenser fan motor if it is not operating.
• Inspect door gasket: Close a sheet of paper in the door and pull it out. If it slides out easily all around, the door gasket may need replacement or adjustment.
• Check frost pattern: Remove the interior rear panel and inspect the evaporator. A full, even frost pattern indicates normal refrigerant charge; a partial or no frost pattern suggests a sealed system issue.

Important: Low refrigerant or a weak compressor requires a certified technician with proper tools to repair and recharge the system.
